ISO7310C Digital Isolator

Texas Instruments' ISO7310C provides galvanic isolation up to 3000 VRMS for 1 minute per UL and 4242 VPK per VDE. This device has one isolated channel comprised of a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry.

This device has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. ISO7310C has TTL input thresholds and operates from 3 V to 5.5 V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of ISO7310C has been significantly enhanced to enable system-level ESD, EFT, surge and emissions compliance.
